Good morning Jörg,
in a project where i work together with WhereGroup we got a problem with
CLUSTER styles and MapServer 8.01:
https://github.com/gisinternals/buildsystem/issues/223
Since you're using also PostGIS as a datasource, maybe its worth a look,
- and the solution mentioned there.
best regards
Stefan H.

Dear list,
I have a problem with clustering of some points (layer at the end of
this mail).
As soon as I insert the block
CLUSTER
MAXDISTANCE 50
REGION 'ellipse'
END
the capabilities-document [1] of the wms ends abrupt with
<sld:GetLegendGraphic>
<Format>image/png</Format>
<Format>im
so I cannot load it to a client.
getmap/browse-mode [2] works fine.
I don't see the reason, does anyone else do and can tell me?
